What exactly are you trying to do? Are you perhaps just looking for -[NSMenu performKeyEquivalent:]?
The behavior of your -menuHasKeyEquivalent:... method is up to you. Are you asking why your method does what it does? We can't know. In any case, calling that should not invoke the action on any target. So: a) I don't understand your first paragraph, and b) the answer to your question in the second paragraph is NO.
The -menuHasKeyEquivalent:… delegate method is mostly not very useful. As discussed in the WWDC 2010 Session 145 - Key Event Handling in Cocoa Applications video (around 6:55), the main use of that method is to return NO for menus that you know do _not_ have key equivalents, to optimize the search.
